Solid fuel hot air generators, known as thermoblocks, burn solid fuels such as coal, pellets, hazelnut shells, walnut shells, vegetable wastes and produce hot air between 50 degrees and 150 degrees in the most economical way, around 20,000 m3 per hour. The hot air produced is used for heating closed areas such as poultry houses, greenhouses, drying ovens, factory buildings, drying paddy and corn in drying silos and wherever hot air is required. They are the most economical hot air generators. Depending on the size of the area to be heated or the drying silo, hot air generators are available in different powers. Solid fuel thermoblocks provide 75% savings compared to liquid and gas fuels.
